Review on DB 5 X60MM HOLE SAW by Francisco Yim

This product is a hole saw only and does not include a mandrel. I had to cut some holes in the trailer to run some tubing which included 3/8" plywood and an aluminum exterior. This will cut out the holes as if they were paper. thicker sheet metal. Again through as if it were paper. After a dozen or more holes I see no difference and no cutting performance Amazing performance for the price.
